I did PM you but wanted to say here on the forum that, in general, I believe, the best sign for an undergrad program is diversity in student work. To me, that signals good teaching that honors the students’ “individual voices.” That said, if you are advanced and drawn to a particular aesthetic, or particularly interested in electroacoustic work, or installations, that would change the schools you might apply to.
Spirit Manager lists some great schools but there are many more. Do you primarily want a conservatory/music school, or a college/university? For a composer, there are arguments for both. It takes many years for a composer to develop, and most go to grad school, so it is also good, I think, to have a long range view, which might include a broader BA, with study of art, literature, history and so on. On the other hand, if you want to get right to it, a conservatory or music school will offer chances to build a resume and make connections (not entirely lacking at BA programs by any means), and weekly lessons (also available at some BA programs). A BM is preprofessional in other words.
I think of NEC, Oberlin (changes happening there with Hartke, see if you like TIMARA), Manhattan School of Music, Purchase, Ithaca, and Bard on the conservatory list, but there are many others. Bard Conservatory requires a double degree. For colleges, Brown, Harvard, Oberlin, Bard, Sarah Lawrence, Columbia- and many more that I will think of as I log off! Mills is quite innovative. U. of North Texas has great electronics. Look at McGill in Montreal too.
Here is a good essay to read on options for music studies in the US http://www.peabody.jhu.edu/conservatory/admissions/tips/doubledegree.html
